There is only three sources of capital to grow your business.  If you want to increase your sales you will need a capital infusion.  Very few businesses have grown their business without some sort of capital being injected to their business.  There are only three sources of capital you can turn to:

a) Investors
You can seek investors to grow your business.  There are two types of investors in the market.  There are investors who want equity from your business.  The other type of investor is seeking a return by providing you with debt capital.

b) Small business loan
A small business loan is a debt.  You can seek a small business loan from alternative lenders or from banks.

c) Revenues
you can also increase revenues to reinvest in your business.  This is very challenging because many businesses just don’t have that extra cash to make a large investment.
